> в хроме не пашет

   try {
                var successful = document.execCommand('copy');
                var msg = successful ? 'successful' : 'unsuccessful';
                console.log('Copying text command was ' + msg);
              } catch (err) {
                console.log('Oops, unable to copy');
              }

А что в консоли у хрома, если не секрет?
